The high-pressure switch (1184656) trips on excessive discharge pressure from a dirty condenser, failed fan, or overcharge; the low-pressure switch (1184655) trips on loss of charge or restricted flow. When a switch fails or sticks open, the unit will lock out and refuse to run, often with no obvious mechanical fault. Symptoms include a compressor that won't start, intermittent lockouts on hot or cold days, or a control board flashing a pressure fault code. These switches are built to original specification with matching trip thresholds and connections.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpec\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Numbers\u003c\/td\u003e\n\u003ctd\u003e1184656 (Pressure Switch Hi), 1184655 (Pressure Switch Lo)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eHigh \u0026amp; Low Refrigerant Pressure Switch Set\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eTempstar (ICP \/ Heil)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFunction\u003c\/td\u003e\n\u003ctd\u003eCompressor Safety \/ Lockout Protection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eHeat Pump, AC Compressor Circuit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFitment\u003c\/td\u003e\n\u003ctd\u003eOEM Direct Replacement\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eCompatibility\u003c\/h3\u003e\u003cp\u003eFits the Tempstar TSH460GKA101 heat pump and other ICP-family units (Heil, Comfortmaker, Arcoaire) that use the 1184656 high and 1184655 low pressure switches.
